I am new to COGNOS and I wish to get certified on it, since my company has recently purchased "IBM FileNet". I will be deploying COGNOS alongside "IBM FileNet" therefore I require some administrative and technical knowledge to carry out routine administrative, maintenance & troubleshooting tasks. Some designing won't do any harm too. If someone has any experience in COGNOS, please lay out a simple plan about how I should pursue COGNOS Certifications. I also need books to study from.

i suggest to follow cognos cookbook, and mc graw hill cognos book, if you are a beginner thease books help you lot....coming to certifications, you can do your basic certification BI-AUTHOR, by following these books.

As far as certifications are concerned, if you are aiming for COG-122, you must go through COGNOS Installation and configuration guide, administrative and security guide as well as architect and deployment guide
